ABSTRACT:
In a method of cutting a workpiece of brittle material with a wire by using a machining solution containing abrasive grains, the workpiece is pushed against the wire from above, and a machining solution pooling vessel is disposed below the workpiece, to immerse the cut portion of the workpiece in the machining solution in the vessel, and an ultrasonic oscillator is provided for the machining solution pooling vessel to apply ultrasonic waves to the machining solution during machining, whereby difficulties that the machined surface is scratched or cracked by the abrasive grains, and the machining solution is deteriorated in cutting capacity are eliminated, and the machining accuracy and efficiency are improved.
